Question

Solve The Following Equations
a)2(x+4)=12
b)3(n-5)=21
c)3(n-5)= -21
d)-4(2+x)=8​

Answer 1

Answer:

Solve the following equations :

a) 2(x + 4) = 12

2x + 8 = 12

2x = 12 - 8

2x = 4

x = 4/2

x = 2

b) 3(n - 5) = 21

3n - 15 = 21

3n = 21 + 15

3n = 36

n = 36/3

n = 12

c) 3(n - 5) = -21

3n - 15 = -21

3n = -21 + 15

3n = -6

n = -6/3

n = -2

d) -4(2 + x) = 8

-8 - 4x = 8

-4x = 8 + 8

-4x = 16

x = 16/-4

x = -4
